MACHINE FOR DRIVING SCREW-EYES.

SPECIFICATION forming part of Letters Patent N 0. 670,361, dated March19, 1901.

Application filed August 9, 1900. Serial No. 26,389. (No model.)

T at whom it may concern:

Be it known that I, EDMUND SATHER, a citizen of the United States, and aresident of the city of New York, borough of Brooklyn,

eyes shall be held in a magazine in quantities,

which magazine forms a portion of the tool, and means whereby thescrew-eyes can be successively fed to an end of the tool and held firmlyin position to enter an object and the screw-eye quickly andconveniently released from the toolafter the screw-eye is fixed inposition. v

Another purpose of the invention is to so construct the tool that it canbe operated by one hand in order that it may be used by awning makersand hangers to especial advantage, permitting them to quickly andconveniently place screw-eyes in position in places which haveheretofore been reached with difficulty.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth, and pointed outin the claims.

Reference is to be had to the accompanying drawings, forming a part.of-this specification, in which similar characters 'of referenceindicate corresponding parts in all the figures.

Figure 1 is a plan view of the improved tool, illustrating a screw-eyevthat has been driven into a support and in engagement with the tool, thetool being just about to be released from the screw-eye and a portion ofthe side of the tool being broken away to show the magazine, in which anumber of screweyes are stored to be consecutively used. Fig. 2 is alongitudinal central section through the improved device 'on the line 22 in Fig. 1, showing the screw-eyes in the magazine in side elevationand one screw-eye in position to be entered into an object. Fig. 3 is aside elevation of the tool opposite that shown in Fig. 2, a screw-eyebeing shown in position to enter an object. Fig. 4 is a transversesection taken practically on the line 4 4 in Fig. 2. Fig. 5 is atransverse section taken practically on the line 5 5 in Fig. 2; and Fig.6 is a detail perspective view of the carrier, which is arranged toslide in the tool and to receive and carry a screw-eye toa position foruse.

The body A of the tool is usually madein two sections 10 and 11. Thebody may be given any cross-sectional shape; but preferably the forwardend of the body is reduced in size and is circular in order that the twoparts may be tied together'at this point by a ferrule 12, secured to thebody by screws 13 or their equivalents. At the inner end of the body thetwo parts are shownattached together through the medium of a singlescrew 14, as is shown in Fig. 2.

r In the upper surface of the body a magazine-15 is produced in thesection 10 at a point near the front end of said body. This magazine isof such shape and capacity that it willaccommodate'a number ofscrew-eyes B, placed one upon the other. Therefore the magazine 15 isprovided with a rectangular section a, which extends longitudinally ofthe body, and a rear circular section a, as is shown in Figs. 1 and 2.The magazine extends to the inner face of the section 10, and alongitudinal channel is made in said inner face, the upper wall of whichchannel has a metal plate 17 secured thereto, usually by means'of screws17 as shown in Figs. 2, 4, and 5. -In this plate 17, which may be termeda wear-plate, an opening 16 is made, conforming to the shape of themagazine 15, the opening 16 being in registry with the inner end of saidmagazine, so that the lowermost screw-eye that is placed in the magazine15 will occupy such a position in the opening 16 in the said wear-plate17 as is shown in Fig. 2. A longitudinal channel is also formed in theinner face of the section 11 of the body, as shown in Figs. 2, 4, and 5,anda wear-plate 19 is secured by screws 19 to the bottom wall of thischannel, and as the channels in the inner faces of the sections 10 and11 are in registry they jointly form a space 18 between the wear-platesof said sections, and this space extends to the outer or forward end ofthe body, as is illustrated in Fig. 2.

At one side of the bodyA the side walls of the space 18 are cut away,and at this pointa plate 20 is secured upon the outer side face of thebody, as illustrated in Figs. 3 and 4,

the said plate having a longitudinal slot 21 made therein. A latch 22 inthe form of a lever is pivoted at a point between its ends by a suitablepin 23 to the under or inner face of the slotted plate 20, asillustrated particularly in Fig. 3, and this latch-lever is adjacent toa longitudinal wall of the slot 21 in the plate 20, and said lever nearits forward end is provided with an inclined projection 24, whichnormally extends across the slot 21 in the plate 20, and the forward endof the latch-lever 22 terminates in an inclined head 25, which normallyextends entirely across the aforesaid slot 21 in the plate 20, as isalso shown in Fig. 3. The latch-lever 22 is normally held in theposition above mentioned by a spring 26, which has bearing against thehead 25.

Preferably metal guards 27 are placed at the side portions of the partsdefining the space 18, near the outer end of said space, as illustratedin dotted lines in Fig. 3 and in positive lines in Fig. 5. These guardsare adapted to prevent wear of the parts defining the space 13, sinceacarrier28 is held to slide in said space between the wear-plates l7 and19. This carrier, which is shown in detail in Fig. 6, is of metal andconsists of a flat body, at the outer end of which a longitudinal slot30 is made, which leads to a circular opening 29, the circular opening29 being adapted to receive the circular portion of the screw-eye to beset, and the slot 230 permits the threaded shank of the eye to extendbeyond the forward end of the carrier. At its rear end the body-plate ofthe carrier is preferably provided with an arm 31, which is shown at aright angle to the body-plate, and this arm extends out through the slot21 in the plate 20 a sufficient distance to be readily engaged by afinger, as shown in Figs. 1 and a.

The top of the magazine 15 is closed by a hinged cover 31, which isprovided with a keeper 32 upon its under face, and this keeper isengaged by a spring-controlled bolt 33, held to slide in a suitablerecess in the upper portion of the section 10 of the body, beneath aplate 3a, in which a slot 36 is made, and the handle 35 of the bolt 33passes out through this slot.

In the operation of the device the magazine is filled with screw-eyes B,and when the carrier or slide 28 is in its normal position within thebody the opening 29 and slot 30 in the carrier will occupy such aposition relative to the bottom portion of the magazine 15 that thelowermost screw-eye will gravitate into the said circular opening andslot. At this time the arm 31. of the carrier will be at the rear end ofthe slot 21 in the plate 20. When the screw-eye is to be placed inposition in an object, the arm 31 of the carrier is forced toward thefront end of the body until the said arm shall have passed theprojection 24 of the latch-lever and bears against the forward At thistime the front end of the slide or carrier 28 will have been carried tothe front of the body, and the shank of the screw-eye will projectbeyond the forward end of the body, as shown in Figs. 2 and 3. The toolmay now be directed as desired and the eye screwed into places whichwould otherwise be exceedingly difficult of access. After the screw-eyehas been fastened in its support the body is drawn from the screw-eye,taking the slide or carrier a sufficient distance beyond the front endof the body to expose the eye portion of said screw-eye. Now by simplyturning the body to one side the slide or carrier may be disengaged fromthe screw-eye. The slide or carrier is then drawn back into the body toreceive another screw-eye for a subsequent operation.

When a screw-eye is to be introduced into a wall or other surface, thehead of the screweye is within the casing, as shown in Fig. 2, and thearm 31 is in front of the projection 24, as is shown in Fig. 3, so thatthe necessary pressure to be exerted on the screw portion of the eyewill not move the arm 31. After the eye has been screwed into thesurface adapted to receive it the arm 31 is carried forward, forcing thehead 25 to one side against the pressure of the spring 26, and thecarrier for the screw-eye is correspondingly forced outward to theposition shown in Fig. 1, whereupon by turning the body of the device toone side the head of the screw-eye is disconnected from the carrier ofthe slide. When the arm 31 is carried as far forward as possible and theslide is in position to release the screw-eye, the spring 26 will havebeen passed to an inactive position by reason of the curved portion ofthe head riding on the spring in direction of its free end. Thereforewhen the carrier or slide is to be drawn in to receive another screw-eyeand the arm 31 is drawn toward the inner end of the body of the devicethe arm will pass over the projection 24-, which is then below the lowerwall of the slot 21, and as the arm 31 is carried rearward it engageswith the heel portion of the latchlever 2 and presses the said heelportion of the latch-lever down, thus bringing the forward portion ofthe latch-lever upward across the slot 21 and again restoring the springto active position.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A tool for driving screw-eyes, having a magazinein its body adapted to contain screweyes, a carrier having slidingmovement beneath the magazine and provided with an opening adapted toreceive the body and a portion of the shank of a screw-eye, the body ofthe device being provided with a passage for the carrier, having onedimension less than the greater cross dimension of a screweye, and alocking device for the carrier, substantially as described.

2. In a machine for driving screw-eyes, a body having a reservoir forscrew-eyes formed therein, a carrier mounted to slide beneath the saidmagazine, said carrier having an opening therein adapted to receive thelowermost screw-eye in the magazine, the said opening being at an end ofthe carrier, the body of the device being provided with a passage forthe carrier having one dimension less than the greater cross dimensionof a screweye, an arm projected from the carrier and extending outthrough the slot in the body, and a latch-lever located at the said.slot, adapted to be engaged by the arm of the carrier.

3. In a machine for driving screw-eyes, a body which serves as ahandle,having a magazine therein adapted to contain screw-eyes, thebottom of the magazine being open, a cover for the outer end of themagazine, a carrier held to slide in the said body beneath the magazine,said carrier having an opening at its end of a shape to receive the headand shank of a screw-eye, which opening is in registry with the bottomof the magazine when the slide is in its inner or normal position,

the body of the devicebeing provided with a passage for the carrierhaving one dimension less than the greater cross dimension of ascrew-eye, a projection from the said slide, which is passed out throughthe slot in the said body, a latch-lever pivoted adjacent to the saidslot, the latch-lever having an inclined head and an offset, both ofwhich are adapted to be engaged by the arm of the slide, the said slidewhen carried outward to one position engaging with the projection fromthe latch-lever, causing the shank of the screw-eye to extend beyond anend of the body, the second outward position of said slide being such asto expose the entire screw- I eye carried thereby, as set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

EDMUND SATHER.
